PUBLICATION 812, FIELD CROP PROTECTION GUIDE, 2020-2021
Publication 812, Field Crop Protection Guide, is the source of pest control information for field crops. The easy to read tables provide information and comments on insect and disease control products for the major field crops including best control options for integrated pest management for each insect and disease.
The information contained in this publication is supplied by Pest and Crop Specialists of the Agriculture Development Branch OMAFRA, University of Guelph Ridgetown Campus, Agriculture and Agri-Food Canada, the Canadian Corn Pest Coalition and the Pest Management Regulatory Agency (Health Canada).
in This Publication
Products listed in this book are registered for use on field crops and are organized by pest for each field crop. Consult each product label before using a pest control product. Labels for registered pest control products are available at the Pest Management Regulatory Agency (PMRA) website at pr-rp.hc-sc.gc.ca/ls-re/index-eng.php.
Within this publication, where rate ranges exist, consult the product label to determine what rate is most appropriate for your pest or disease situation.
The Pesticide Label
Consult each product label before you use a pesticide. The label provides specific information on how to use the product safety hazards, restriction on use, compatibilities with other products, the effect of environmental conditions, etc. The pesticide product label is a legal document. Follow all label directions.
Crop group information
A crop group is a grouping of plant species based on botany and taxonomy (e.g., plant families), as well as on how the crops are produced. Crop groups are often further divided into smaller and more closely related subgroups. A pest control product may be registered on a subgroup, rather than the entire crop group. Crop groupings are used primarily to set maximum residue limits and establish a common pre-harvest interval (PHI) for a similar set of crops. It is important to remember that not all products have a crop group registration, and products registered on one crop are not necessarily registered on all members of its crop group. There are some crops that do not belong in a crop group. A complete list of all crops included in both original and revised crop groups can be found on the Health Canada website: www.hc-sc.gc.ca/cps-spc/pest/part/protect-proteger/food-nourriture/rccg-gcpcr-eng.php.
